. CALENDAR,

Application filed February 2, 1322. Serial No. 533,587. I i I To allwhom it may concern I Be it known that 1, Leo OPPENHEIM, a citizen ofthe United States, residing at New York, county and State of New York,have invented a new and useful Improvement in I Calendars, of which thefo'llowingis a speciend the invention consists in combining anindicating device with a casing adapted for holding anddisplaying monthsheet and so arranging the several parts-as to admit of the indicatingdevice operating over the face of the month sheet.

Other objects will appear from the following description, referencebeing had to the accompanying drawings inwhich- Figure 1 is a frontelevational view of the invention. I

Figure 2 is a horizontal cross sectional view and i I i I 1 Figure 3 isa contracted plan view of the indicating device.

Heretofore in calendars of this sort a flexible strip orweb was providedwith a series of lines arranged in echelon in order that expired dateson a date sheet arranged behind may be cancelled and by means of theselines, the present date is indicated. This arrangement has not provenentirely satisfactory because the series of cancellation lines passingover the expired dates act to partially obliterate the dates, therebymaking them obscure and rather hard to see when one wishes to refer to apassed or cancelled date. The present inventor who is also the owner andmanufacturer of the above mentioned calendar has by means of the presentinvention overcome this objec-' tionable feature by doing away with thecancellation lines entirely and providing the fiexible web with a seriesof circles forming bulls eyes within which appears the present date ofthe month which may be readily distinguished at a glance. Through thismeans it is obvious that the passed dates are alays visible for readyreference when occasion requires.

The casingv a may. be formed of 'anysuit-J able sheet material such aswood, and the specification of Lettersilatent. Patented :May 9,1922;

base block 5 may be of. the same orodifferent material. Said baseblock'may be integral with or otherwise connected to the casing and bypreference is formed withan oblique upper-face 6 or otherwiseconstructed so as to give a pitch or tilt to the casing, to; maintainthelatter more directly in the line pf vision'when resting upon a desk, orthe ike.-.

Thebase and casing may be covered with anygsuitable material such asleather, :or otherwise decorated so as to lend, to the .at-

'tractiveness of the device.

The'casing a is interiorly provided with a pocket 7 which is open at itsends and topand the inner sideof which is formed by aplate 8 arrangedsoas to form a support for the month sheets 9, the latter being of anyapprovedconstruction and if desired provided with printed matter inaddition to what .is required for indicating the days, i

dates and name of any month. A number of cards corresponding to thenumber of months .in one or more years may be employed or successivemonths may be printed on the opposite faces, 'The pocket? andthejopening in theiupper end=thereof are of such size as to readilyadmit of the in-' troduction thereinto of the month sheets, and

the upper side portions of the latter project through the open upper end10 of the pocket to present convenient finger holds when changing orarranging thesheets.

The front side' 11 of the pocket has an opening 12 whose area is suchthat all the necessary printed'matter on the surfaceof the sheet may beseen. I I lnterposed between the month sheets and the outer side 11 ofthe casing is a highly transparent indicating web ,13 formed of suitablematerial, such as very thin celluloid, The width of this web is at leastequal to the. combined .width of the longitudinal rows of figures on anymonth sheet and preferably will be greater than that of the opening 12.The end portions of the web are connected to drums 15 and 16, arrangedin compartments 17-17 which communicate with the pocket '7, the lowerends of the drums being provided with -trunnions 18,

supported in bearings in the bottom of the said compartments. The upperends of the drums are also provided with trunnions 19 which pass throughbushings .20 in the top 10 of the casing and are surmounted with millednuts 21 forming convenient turning means for the drums.

Associated with the trunnions 19 of the drums are friction devices inthe form of coil springs 22 which are arranged so as to contact with theinner surface of the casing, to prevent accidental movement of the drumsunder a tendency of the indicating web to coil or bend between the drumsafter the setting or adjusting of the web.

To additionally prevent any buckling or bending of the indicating weband to pro tect the same from damage resulting from direct handling, orblows or the like, a panel 26 of glass or other transparent material isinterposed between the web and front wall 11 of the casing. v

As shown in Figure 3 the transparent indicating web is provided with aseries of circles 23 forming bulls-eyes arranged in echelon or step formso that when the web is moved from left to right (Figure 1) across thenumerals on the visible month sheet, the numerals will appear within thebulls eye successively, and stand out promptly when encircled thereby.The horizontal interval between any two bullseyes is equal to thehorizontal length of the date sheet.

In use, the surface having imprinted thereon the desired month, isarranged so as to be visible through the opening 12 and through thetransparent web 13. Now, we assume that this arrangement is made on thefirst day of the month, then the web will have been turned until thefirst bullseye encircles the numeral 1. Now, upon the passing of thefirst day the operator turns the knob on the right in Figure 1 and thebulls eye passes from the numeral 1 and encircles the numeral 2, thusindicating that it is the second day of the month. This action isrepeated on the second and subsequent days so as to indicate the dayssuccessively, it being obvious that the past days are visible cancelled.Upon the passing of the last day of the month, the month sheet is turnedor replace-d as the case may be, so as to have the surface provided withmatter for indicating the succeeding month, visible through the opening12 and at such time of arranging the cards the web is op erated tore-set the indicating device as previously described.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is In a calendar, the combination of a casing having anopening in the front side thereof, a month sheet removably mountedwithin the casing and visible through the opening and a movableindicating web mounted within the casing and arranged over the visiblesurface of the month sheet, said web provided with a series of circlesarranged in echelon in order that dates on.
